10 lectronic Premon S range lectronic trip units that offer sophisticated protective functions and wide setting bands are standard protection devices for the 400, 630, K800, K250 and K600 frame sizes. The frame can be equipped with interchangeable trip units offering a choice of the electronic or the electro-mechanical device. ach electronic device has been designed with the abnormalities of modern low voltage distribution circuits in mind and has been rigorously tested to cope with harmonic currents, electro magnetic fields, inrush currents and spikes, thus preventing phenomena as incorrect current measurement and nuisance tripping. The devices exist in a number of performance tiers, the Premon S device for the and frame sizes, the SMR 2 for the frame size and the SMRe, s and g types for the K frame size. Premon S Premon S is an interchangeable electronic trip unit designed to offer uncompromising reliability in all network environments. It combines sophisticated 32 bit technology with a complete set of protection functions. Simple dials provide access to a wide setting range of 0.3 to times In. esigned to fit the Record Plus line of moulded case circuit breakers, the devices are available as 3 or 4 pole units in a current range of 7 to 630. ach standard unit has between two and four overcurrent protection devices: n overload protection (LT) with a range of LT=Ir[] ST..x Ir = Im I 2 T O I 2 T ON O x Ir = Ig [ms] Pickup/rror 500, to times the chosen trip unit rating (). ach of the possible 5 positions has a rating mentioned in mps. delayed short-circuit protection (ST) with a wide setting band of 2 to 3 (2) times the LT device setting or Ir value. fixed time setting per breaker size is applied. selective instantaneous device (I) set at a fixed value of 4 (2) times the chosen trip unit rating, using waveform recognition to assure selectivity. n optional ground fault protection device () (residual principle) can be set from 0.4 to times the chosen trip unit rating and be used with multiple delay and/or I 2 T settings. ach device is equipped with a L indicator that flashes when the current reaches 0.95 times Ir and illuminates constantly when an overload trip is imminent (at.05 times Ir). The electronics also continuously perform self diagnostics and warn the user of any defect by the L indicator. n integrated temperature sensor prevents the electronic components from reaching temperatures that could damage the breaker or it's surroundings. Seconds 50,000 5,000,500 0,50 0, mperes Premon together with the unique selective and current limiting line of Record Plus line circuit breakers offer strongly improved selectivity between upstream and downstream devices. The use of highly accurate sensing technology and of state-of-the-art electronics, reduces the tolerances on expected tripping currents and the associated time spans to a minimum. The result as depicted in the time current curve: selectivity up to,000 between a upstream breaker set at 80 and a downstream breaker set at 45. Premon makes selectivity possible between downstream and upstream devices with a ratio between settings of.25. Selectivity on higher currents is assured by the unique selective and current limiting properties of the implemented Record Plus 630 (set at 80) and 60 (set at 45) circuit breakers. Integrated test kit Simply connect a standard mobile phone charger (3) to the micro US port and the "TST" button goes live. epress it and it checks the full electronic circuit and then trips the connected breaker. Integrated "TST" function that only needs a US phone charger. The US port also functions as a data access port, allowing the user to verify the breaker settings. The data are covering last fault occurrences and waveform data of the last event (4). In this configuration, the P powers the trip unit (charger no longer needed). Prepared for the future Premon S is the first of a new generation of Record Plus trip units. They are interchangeable, designed to allow for future upgrades and have a user definable neutral protection (4 pole devices only). Premon S () Version without LT protection is available.

13 lectronic SMR2 range The SMR2 is an electronic trip unit offering a fixed set of sophisticated protective functions that can be extended at will by the addition of seperately available modules. esigned for use with the 400 and 630 frame sizes the device has a fixed set of 3 protective functions allowing a selective and fully adjustable protection against Overloads (LT) and short- circuits (ST and I). oth the LT and ST protection can be set to different time settings or bands (LT and ST) whilst the ST device can be switched to a energy protection mode (I 2 t). The SMR2 uses rating plugs that give the user the flexibility to make a last minute choice in the required current rating, protected poles or protection band. 24V auxiliary supply can be connected to the trip unit via the contact module. This enabling all modules to be used to their full capacity and allowing the use of the ZSI function (if installed in the trip unit). Overload protection LT (long time) The Long Time or overload protection is adjustable from 0.4 (0.64 () ) to x the chosen sensor ratings in 6 (32 () ) steps. The user can also define one of 6 time bands (LT) each designed to match specific loads, motor or cable characteristics. Of these 6 time band settings, 4 have time bands for line applications and 2 are dedicated to motor protection (for time band classes see N ). When set to motor protection mode, a phase loss protection is initiated ll SMR2 trip units have a built-in temperature sensor that trips the breaker at temperatures above 90. It thus prevents the breaker and electrical components in its immediate vicinity from overheating. The SMR2 is also equipped with a so called thermal memory device. This memory tracks overheating even after the device has tripped and prevents the breaker from being switched whilst its environment is still at a too high temperature. Short-circuit Protection ST (short time) Offerering a selective protection against low value short-circuits the Short Time protection is settable from.5 to 2 (2) x the adjusted LT protection (Ir). The device can be set to five time setting bands (ST), this allowing selectivity between different breaker sizes. The ST device can be set to an 'energy curve mode'. This mode changes the fixed delay and reaction time value of the device, when the set current level is reached, into a reaction time that depends on the energy flowing in the circuit. Short-circuit Protection I (instantaneous) Offerering a protection against short-circuits the Instantaneous protection is settable from 2 to 3 (3) x the chosen sensor rating. This hi speed tripping device will not react to the first short circuit peak but will only initiate a trip signal after a second short circuit peak is detected. iscrimination is thus always ensured. ll Record Plus devices are equipped with a HIOS (hi set Instantaneous) protection device. This device mechanically trips the breaker when a short circuit is detected of a value exceeding the capabilities of the breaker in which it is installed and initiates a current limiting interruption of the fault. that will trip the breaker when the difference in current between one phase current and the other phases exceeds 80% for more than two seconds. This easy-to-adjust trip unit is equipped with a LT load indicator device that operates by means of two L indicators located on the trip unit front face. If the load reaches a 60% of the set Ir value, a green L will start to blink (3 flashes a second). When the load reaches 75% of Ir it will stop blinking and remain on. The second orange L will start to blink at 95% of the Ir value. It will remain on when the load reaches 5% of Ir and a trip is imminent. The combination of these two protection devices and the unique current limiting propeties of the Record Plus breaker improve Selectivity whilst maintaining urrent Limitation. ach SMR2 trip unit comes with a transparent, tamper-free (sealable) cover, this to prevent unauthorized manipulation of the breaker settings. They are supplied as a simple to mount, plug-in electronic pouch (current sensors supplied with the breaker). The device is supplied with an actuator with flux shifter that fits into a pocket in the breaker housing and is then connected to the trip unit. Without a mounted and connected actuator coil the breaker will not function. In order to verify a correct operation of the combination a simple device is available to test the assembly. We strongly recommend the use of this test device. () Normaly supplied with two rating plugs, each with a setting range of (2) Some types limited to x (3) Some types limited to x.4

15 SMR2 range 400 and 630 dvanced lectronic Trip Unit SMR2 (continued) Modules ach SMR2 device can be equipped with two plug-in elements, a rating plug and an extension module. The extension modules are simple plug-in devices that allow the user to enhance the SMR2 as a protective device or to add in extra functional features. There is a range of functional modules each adding two functions to the device. this allows an SMR 2 to be equipped with: round fault Protection Load shedding across two channels Trip Reason indicators ommunication (modbus RTu) ach module has a low level electronic output that can be channeled through the communication bus (when present) or in some cases trigger a /250 Volt changeover contact placed in an external contact module containing four contacts (type MM). round fault protection esigned for protection against indirect contact, the ground fault device measures the vectorial sum of the three phase currents and, if present, that of the neutral conductor. If the sum of these values exceeds the set current thresholds for a period of time greater than the set time delay, the breaker is tripped. The round ault protection option is adjustable from 0.2 to x the chosen sensor ratings in 9 steps. The user can also define one of 5 delay time bands () designed to allow selectivity between different sensor ratings. The device can be set to an 'energy curve mode'. This mode changes the fixed delay and reaction time value of the device, when the set current level is reached, into a reaction time that depends on the energy flowing in the circuit. Load shedding device The Load Shedding device (R) is designed to allow the user to switch off non priority loads before the LT function trips the breaker due to an overload. It measures the current within the circuit and provides a signal if the current measured in the three phases exceeds the set current values. The device has two channels, both adjustable from 0.55 to x the set LT protection value (Ir). ach channel is equiipped with a time delay directly proportional to that of the LT setting. hanel is set to a time delay equal to LT/2 and channel two is set to a time delay of LT/4. If the current drops below the set thresholds the signal is reset. The reset signal being given in a time proportional with the chosen LT curve. signal due to a load shedding event can be channeled through the communication output (when present) or be wired out to the contact module. (type MM) Trip Reason Indicators In order to indicate the reason of a breaker trip a set of total of three L's are provided on the trip unit front face. One indicating a trip due to the LT device, one indicating a trip due to the ST device and one for the I device. Without auxilliary power, the use of the trip reason button is necessary to light up the appropiate L. With auxilliary power the use of the trip reason push button is unnecessary. The three trip signals can be channeled through the communication output (when present) or be wired out as an overload (LT) or short circuit signal (ST and I) to the contact module (type MM) ommunication When the communication option is added to the SMR2 trip unit the following data can be viewed: - The position of the switches on all installed devices, thus providing the settings of the breaker. - Signals indicating on which of the installed protection devices the breaker has tripped. - Load shedding orders. - Zone selective interlock occurrences. or each breaker with Modbus rtu the use of a internal communication module N and external contact module type MM (see page.24) is required. 24V auxiliary supply is needed that supplies the system through the external contact module..6

16 Zone Selective Interlock device that allows the user to achieve selectivity combined with the fastest possible fault reaction time. When the ZSI is active the SMR2 trip unit will always trip the breaker as quickly as possible, ignoring the time delays set by means of the ST or devices. However, when a ZSI signal is received from a downstream breaker equipped with an SMR2, the ST or of the upstream SMR2 device revert to wherever the adjustment is set. With standard cables the distance between breakers is a maximum of 30 meters. The use of shielded cables allows the distance between breakers to be increased to km. maximum of five SMR2 trip units can be linked in this manner. The ZSI option requires a 24V auxiliary supply. One MM module connected with one of the breakers in the ZSI loop can be used. The MM needs then connected to an auxiliary supply of 24V. When the breaker is equipped with a "OM" option the ZSI status signal is also available on the communication output.

19 lectronic trip units K800 - K600 lectronic Trip Unit SMRe, s and g Non inter changeable electronic designed to allow the user to conveniently tailor the protection device to match individual circuit requirements. The available options include adjustable overload pickup values, overload trip time characteristics, short time pickup circuit values, short time delay circuit trip times and energy values. The trip unit can be equipped with a ground-fault protection and provides a flexible solution to all protection scenarios. This easy-to-use trip unit with overload and selective short-circuit protection is equipped with an overload signalling option and has a built-in temperature sensor to prevent the breaker and electrical components in its immediate vicinity from overheating. The 4 pole units are equipped with a switchable neutral protection option, allowing the user to set the neutral at 0.50 or % of the phase ratings. Overload Protection (LT or Long Time) esigned to meet the newest I installation regulations all variants can trip the breaker with 5 seconds at 8 times the LT setting (Ir). The SMRe is supplied with this 5 second time band whilst the SMRs and g variants have 4 selectable time bands that trip the breaker within 5,, 20 or 30 seconds. The device is adjustable from 0.4 to x the breaker (In) or Ict rating in 9 steps. ll SMe, s or g trip units have L's indicating that the Trip unit has powered up (green) and a second L that provides information on a imminent tripping event. This L flashes at three times a second when the current reaches 95% of the breaker setting (Ir) and will remain fully lit when 5% of this values is reached. If the temperature in the electronic circuits reaches 75 degrees centigrade both L's light up simultaneously whilst a trip is initiated once the temperature exceeds a 90 degree centigrade limit. third L located in the vicinity of the LT setting knob indicates a breaker trip on an overload event. Timed Short icuit Protection (ST or Short Time) Offering a selective protection against low value shortcircuits the Short Time protection is settable from.5 to x the adjusted LT protection (Ir). The SMRe has a fixed time band of millisecond's. setting that allows discrimination with downstream devices. Tthe SMRs and g variants have a choice of four time setting bands (ST), designed to allow selectivity between different breaker sizes. Here the ST device can be set to an 'energy curve mode' that changes the reaction of the device from a fixed delay and reaction time value when the set current level is reached to a reaction time that depends on the energy flowing in the circuit. HIOS Tripping evice (If setting) ll Record Plus devices are equipped with a HIOS (hi set Instantaneous) protection device. This device mechanically trips the breaker when a short circuit is detected of a value exceeding the capabilities of the breaker in which it is installed and initiates a current limiting interruption of the fault. This device once combined with unique current limiting propeties of the downsteam Record Plus breaker provide a high level of Selectivity whilst maintaining urrent Limitation. round ault Protection () esigned for protection under fault conditions the ground fault device measures the vectorial sum of the three phase current and, if procent, that of the neutral conductor if the sum of these values exceeds the set current thresholds for a period of time greater than the set time delay, the breaker is tripped. The round ault protection option is adjustable from 0.2 to x the chosen breaker rating (Ict) in 9 steps. The user can also define one of 4 delay time bands () designed to allow selectivity between different sensor ratings. The groundfault device is available in the SMRg trip unit type. Zone Selective Interlock device that allows the user to achieve selectivity combined with the fastest possible fault reaction time. With connected ZSI the SMRs and SMRg trip unit will always trip the breaker as quickly as possible, ignoring the time delays set by means of the ST or devices. However when a ZSI signal is recieved from a downstream breaker equipped with an SMR s, g or 2 the ST or of the upstream device are reset to the previously ignored original and ST timings. The round ault and Short Time Zone Selective Interlock signals are shared on one in/out put. The device only works when auxiliary power is present and operates up to a distance between breakers of kilometer. The use of shielded cable is required. maximum of five SMR s, g or SMR2 trip units can be linked in this manner. (not available in the SMRe) onnection of trip unit ach SMRs and Trip Unit has a connector located on the right side of the breaker.
